This OE Match rear wheel carrier bush is a replacement suspension bush for Porsche 997 rear wheel carriers. It has an 85 sports shore rating, making it suitable for drivers looking for a firmer, more performance-focused replacement compared with a standard soft rubber bush.
Fits:
Porsche 997 Carrera MKI & MKII 2005-10 COUPE / TARGA / CABRIO
Diagram ref no 1
The wheel carrier bush supports the connection between the rear wheel carrier and suspension assembly. It helps control wheel movement, absorb road vibration, and maintain rear suspension geometry. The firmer 85 shore rating helps improve suspension response and rear axle control while still allowing controlled movement within the suspension system.
Functions
• Replaces the rear wheel carrier bush
• Supports the rear wheel carrier within the suspension assembly
• Helps maintain correct rear suspension geometry
• Improves rear axle stability and response
• Helps reduce unwanted wheel carrier movement
• 85 sports shore rating for a firmer performance feel
• OE Match replacement for rear suspension repair or upgrade.
Why Replace This Part?
Wheel carrier bushes are exposed to road load, suspension movement, moisture, heat, and age-related wear. Over time, the original bush can soften, crack, split, perish, or develop excessive movement. A worn bush may cause vague handling, rear-end instability, knocking noises, poor alignment control, or uneven tyre wear. Replacing the bush helps restore suspension precision and supports more stable handling.
When to Replace This Part
• The original wheel carrier bush is cracked, split, worn, or perished
• Rear suspension movement or play is present
• Knocking or clunking is heard from the rear suspension
• Rear wheel alignment does not remain stable
• Tyres show uneven or accelerated wear
• The rear wheel carrier has been removed or serviced
• A firmer sports suspension bush is required for improved handling response.
Where it fits on the car
This bush fits in the rear wheel carrier on Porsche 997 models. It is suitable for use with wheel carrier part numbers 99733111107 and 99733111207, according to the vehicle’s rear suspension layout.

OEMatch Front Sub frame — Fit, Function, Confidence
OEMatch front sub frame components for Porsche models support the main chassis structure around the engine, suspension and steering systems, helping the car feel stable and precise in everyday use.
- Front sub frame carriers and crossmembers for Porsche applications
- Associated mounting and hardware items where applicable
- Options to support repairs, refurbishment and project builds
Understanding OEMatch Front Sub frame
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original front sub frame. OE (Original Equipment) refers to parts matching original specifications for the front sub frame and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM front sub frame engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. The front sub frame forms a structural cradle that locates key running-gear components, so correct geometry, stiffness and mounting positions are important to how the car drives and how loads are transferred into the bodyshell. Over time, exposure to road debris, moisture and mechanical loads can cause corrosion, distortion or damage around this area, especially on higher-mileage or hard-used Porsche models. OEMatch focuses on front sub frame components engineered to match the original form, fit and function for Porsche applications, giving a practical alternative when maintaining or refurbishing the underside of the vehicle.
- Components made to original-spec dimensions for consistent alignment
- Direct-fit replacements engineered to match original dimensions and tolerances
- Fits original mounting points and clearances
- Compatible with factory systems and sensors
Why Front Sub frame Wear and Fail
- Corrosion from water, road salt and trapped dirt in seams or cavities over many years
- Impact damage from kerbs, debris or minor collisions affecting alignment or structure
- Fatigue from repeated suspension and braking loads leading to cracks or deformation
The Importance of Replacing with OEMatch Front Sub frame
Replacing a worn or damaged front sub frame on a Porsche helps maintain suspension geometry and steering precision, supporting predictable handling and even tyre wear. Addressing corrosion or accident damage early can prevent further deterioration around adjacent mounting points and fasteners. Many owners search for genuine or OEM front sub frame; these are direct-fit alternatives designed to match the original form, fit and function. Selecting suitable components from OEMatch allows targeted repair work or more extensive refurbishment when restoring or upgrading an older Porsche, while keeping the focus on compatibility with factory layouts.
- Supports correct alignment of suspension and steering pick-up points
- Helps reduce unwanted movement and noise from distorted or weakened structures
- Offers a straightforward route to refresh corroded or accident-damaged areas
Support & Advice
Fitting can appear straightforward but may require specific procedures such as torque settings, alignment, balancing or recalibration. If you lack the correct tools or experience, a qualified technician should carry out the work, following model-specific procedures. Recheck fasteners after an initial period of driving.
